[Isolation of foamy virus type II out of haematopoetic cells from baboons with haematoblastoses and from healthy animals (author's transl)].

Foamy virus Type II persists in the haematopoetic organs of 75 percent of baboons in the Suchumi flock. A mixed infection with foamy virus types I and II seems to be possible. Foamy viruses are isolated as well from monkeys with haemoblastoses as from healthy animals. New information concerning the intrauterine transmission of foamy viruses were obtained.
